MACHINE FOR DRESSING STONE.

SPECIFICATION forming part of Letters Patent No. 395,843, dated January8, 1889.

Application filed July 13, 1888. Serial No. 279,855. (No model.)

To aZZ whom, it may concern.-

Be it known that I, FRANK MANNING, a citizen of the United States,residing at Narberth, in the county of Montgomery, State ofPennsylvania, have invented a new and useful Improvement in Machines forDressing Stone, which improvement is fully set forth in the followingspecification and accompanyin drawings.

IO My invention relates to improvements in machines for dressing stone,and the objects of the invention are to provide improved mechanism forcausing the carriage to travel longitudinally and transversely, or at aright 1 5 angle to said longitudinal or horizontal travel; further, toprovide an improved construction of carriage and mechanism for operatingthe hammeror cutter, and also mechanism for throwing thehammer-operating mechanism into or out of operation, as desired;further,

to provide an improved construction of cutter or hammer; and, further,to provide an i111- proved construction of stone-carrying trucks.

The invention consists of the novel con- 2 5 struction and combinationof parts hereinafter described, and specifically claimed.

Figure 1 represents a top plan view of .a machine for dressing stoneembodying my invention. Fig. 2 represents a side elevation 0 thereof.Fig. 3 represents an end view of a detached portion on an enlargedscale. Fig. 4 represents views of the hammer or cutter. Fig. 5represents an end view of the carriage. Fig. 6 represents an end view ofthe stone- 3 5 carrying truck.

Similar numerals of reference indicate corresponding parts in theseveral figures.

Referring to the drawings, the frame of the machine comprises theparallel bars 1, the

connecting-bars 2, and the supports or legs 3.

In one end of the frame is journaled the driving-shaft 4, carrying thepulley 5 and loose pulleys 6. 011 said shaft 4 is mounted a pulley, 7,and worm-wheels 8. The worm-wheels 8 mesh with worm-gears 9 in inclinedshafts 10, having their bearings in boxes 11. The shafts 10 carry bevelgear-wheels 12, which mesh with bevel gear -wheels 13 and 14 mounted ona shaft, 15. The bevel gearwheel 13 is loose on said shaft, and is cutout at 13*, the purpose of which will be explained,

and the bevel gear-wheel 11L is secured fastto the shaft 15 and revolvestherewith. Connected with the shaft 15 is a collar or flange, 15provided with a projection, 15, the purpose of which will appear.

16 represents a sleeve surrounding the shaft 15, and adapted to revolvetherewith. This sleeve carries the sprocket-wheels 17, one of which isprovided with openings 17 adapted to receive the arms or pins 18 on theclutch 18*. The clutch 1S is provided with an extension, projection, orlug, 18 adapted to enter the cut-out portion or notch 13*, anda cut-outportion or notch, 18*, adapted to receive the extension or lug 15, andis provided 011 its periphery with an annular groove adapted to beengaged by the shiftinglever 18, for the purpose well known.

In the other end of the frame is fixed a shaft, 6?, and running loose onsaid shaft are the sprocket-wheels 17 and the belt-pulley 7*. Over thepulleys 7 and 7 travels the belt 7 hereinafter more fully referred to,and over the sprocket-wheels 1'7 and 17 travel belts, bands, or chains17 From this construction it will be seen that the driving-shaft isrevolved by means of the driving-pulley imparting motion to thesprocket-wheels and causing the belt 7 to travel and also the chains 17It will also be seen that when the clutch 18 is caused to have the lugengage the cut-outportion 13 of the gear-wheel 13 the sleeve and chainsare then caused to revolve at the same speed as the said gearwheel 13,and that by causing the collar 15 to have its lug 15 engage the cut-outportion or notch 18 of the clutch 13 the sleeve 16 will be revolved atthe same rate as the shaft 15 upon which it is mounted; and also 0 thegear-wheel 14, as will be readily understood.

1 9 represents the carriage mounted on wheels 19 adapted to run on theparallel bars of the frame. 7

20 represents the carriage-frame provided with the rack 21 011 the underside, adapted to be engaged by the pinion 22 on a shaft, 23, carrying aworm, 24, operated by the worm shaft 25. The worm-shaft which operatesthe worm is preferably revolved by means of a wrench adapted to fit inthe end of the said having thehelt 30* attached to itsends. This i heltBo is connected with the hammer ll, which is provided with the heveledportion 5 adapted to slide in dovetailed. ways 32 on the carriage-frame.The hammer is of peculiar construction, and consists of the clampingjaws31 having their contact-faces curved and adapted to receive the curvedor cylindrical arm or post 31" of the cutter 31 By thus constructing thejaws and cutter it ing-jaws hy means of the screw-holt and jamnut ill",and thus made to dress the stone to suit convenience.

33 represents a helt-pulley loose on the shaft 27, and this pulley iscupped to receive the clutch 33*, which is connected with the shaft bymeans of a key engaging the keyway 27* of the shaft, and is adapted torevolve said shaft. The clutch is provided with an annular groove, l -iand in said groove is received the upper end of the shifting-lever ll.The ,5 shifting-lever is tulerumet'l to an arm or extension, on one ofthe uprights 26. In order to retain the lever in the position to whichit has heen shifted,l provide the lever 3U, which is flllCllillllGtl tothe shifting-lever and .o carries a lug or stud, 36", which passesthrough openings in the shifting-lever, and is adapted to engage any oneof the series of openings 37 in the plate 37 secured to thecarriageframe, and to hold the clutch out of ctmtact with thedriving-pulley I attach a spring, 37,

to the plate and shitting-lever. From this construction it will henoticed that the lever can he shifted to cause the. clutch to engage thepulley, and thus cause said pulley to drive 0 the shaft, or can heshiftta'l to throw the pulley out of o 'ieration also, that; the amountof clutching-powerhetween the pullev and clutch can he adjusted by meansof the shifting-lever and adjusting devices.

5 The operation is as follows: The stone in its rough state is placed onthe trucks and adjusted hy means of the screws to the proper height. Thecarriage is also adjusted to bring the cutters in proper position foracting upon 0 the stone. The chains 17 pass over the sprocket-wheels, asshown, and are ctmnected with the carriage. The driving-belt passesaround the pulleys in the frame and under and over the pulleys on thecarriage-frame, as

5 shown. Theshifting-leverisoperatta'l to throw the clutch intoengagement: with the pulley a )r), By the action of the chains 17* thecarriage caused to travel horizontally, and the drivinghelt revolves thecrank-wheel which o 'ierates the mechanism connected with the cutters,causing the same to cut: the stone as the carriage travels along. Thecarriage is then returned, the worm-shaft operated to cause the carriageto move transvta-sely, ready to dress a new surface on the stone. Thecarriage travels ln'irizontal ly, as hefore, and the cutters operateupon the stone in the manner descrihed until the entire surface hasdressed, as will he readily undm'stood.

From the peeuliarconstruction ot' the stonesup n'irt of the truckshaving the depressions or recesses, with the heads of theadjustingscrews arrangtal therein, it; will he seen that either side ofthe support may he elevated to present either edge of the stone to theaction of the cutter, and that. the stone mayhe raised in a horizontalor inclined plane, as desired,

, and thus permit the entire surface of said is evident that the cuttercan he turned to any angle desired, and retained in theclamp- 1 stone tohe operated upon, or the edges thereof, and this is a great advantage.
